Sorry for that. But Windows 11 has a set of hardware requirements the computer should meet in order to run Windows 11 smoothly. The main reason you can't install Windows 11 on a AMD processor is the CPU compatibility issue. Windows 11 officially supports AMD Ryzen processors starting from 2nd generation (Zen+) and newer. The Ryzen 7 1700X is a 1st-generation Ryzen (Zen, 2017) CPU, which is not on Microsoft’s supported CPU list.

Another common blocker is TPM 2.0 and Secure Boot. Many older AM4 motherboards shipped with TPM disabled by default, or only support firmware TPM (fTPM) with limited compatibility. Even if TPM can be enabled in BIOS, Windows 11 setup will still fail if the CPU itself is unsupported.

That said, the CPU is still powerful enough to run Windows 11 in practice. Many users install it by using unsupported installation methods (registry edits, modified installers, or upgrade tools). Just keep in mind that Microsoft does not guarantee updates or long-term support on unsupported hardware.
